Weather Journal: Mostly Sunny Skies on the Sandy Anniversary

Skies stay mostly sunny on Tuesday in Greater New York, but cooler temperatures and shorter days serve as a reminder that winter is on its way.

A cold front will cross the region late on Tuesday. On Wednesday, high pressure builds in from Southern Canada, bringing clouds and cooler temperatures but no precipitation.

The extent of Tuesday’s cloud cover will vary across the region, but it’s safe to expect partly to mostly sunny skies. The arrival of the polar air mass will keep temperatures several degrees below seasonable levels. Highs reach into the upper 40s in the interior and into the lower 50s in New York City and along the coast. If cloud cover errs on the side of mostly rather than partly, temperatures aren’t likely to climb out of the 40s for most of the region.

Evening will also be party cloudy, with a low around 45 in New York City and closer to 35 in Trenton and New Haven. And east wind at 3 to 5 mph cools the region further and there’s a 20 percent chance of showers after midnight. Clouds increase on Wednesday, but the chance of precipitation will remain slim.
